Smallholder Pig Rearing Systems in Northern Lao PDR
Phengsavanh, P.,Ogle, B.,Stur, W.,Frankow-Lindberg, B.E.,Lindberg, J.E. Asian Australasian Association of Animal Productio 2011 Animal Bioscience Vol.24 No.6
This paper describes the results of a survey aimed at characterizing smallholder pig production systems in northern Lao PDR. A total of 341 households from five Northern provinces were interviewed in the survey. Village meetings and individual interviews, using a semi-structured questionnaire, were used to collect information. Three main pig rearing systems, free-scavenging, semi-scavenging and confinement (enclosures and pens), were found in the survey areas. These systems were practiced differently by smallholders depending on the level of intensity of crop production, ethnicity and purpose of keeping pigs. The confinement system was mainly practiced by Lao-Tai and Tibeto-Burman groups, who mainly bought piglets and fattened these pigs for sale. In contrast, the Mon-Khmer and Hmong-Mien reared pigs in free-scavenging and semi-scavenging systems, and usually keep sows for piglet production. The main factors that affected the changes in rearing systems were found to be level of intensity of crop production, local regulations and outbreaks of disease. The main constraints found in smallholder systems were outbreaks of disease, high mortality of piglets and the slow growth rate of fattening pigs.

YIELD AND DIGESTIBILITY OF FORAGES IN EAST INDONESIA I. LEGUMES
Bulo, D.,Blair, G.J.,Stur, W.,Till, A.R. Asian Australasian Association of Animal Productio 1994 Animal Bioscience Vol.7 No.3
This study was undertaken at Gowa, South Sulawesi, Indonesia as part of a larger forage genetic resource evaluation project. The experimental program consisted of a field experiment where grasses and legume species were grown in monocultures and the yield, N content and rumen bag digestibility using goats were measured. The field experiment was conducted from December 1985 to October 1986. Eight species of legumes (Desmodium heterophyllum cv. John-stone, Desmodium triflorum from Gowa, South Sulawesi, Arachis sp. from Maiwa, South Sulawesi, Clitoria ternalea CPI 50973, Macroptilium atropurpureum ev. Siratro, Neonotonia wightii cv. Tinaroo, Centrosema pubescens CPI 58575, Centrosema plumeri CPI 58568) were grown as monocultures. After establishment all plants were cut to a uniform height of 5 cm, and subsequent cuts were made on regrowth after 14, 28, 42, and 56 days (cycle 1). Cycle 2 commenced towards the end of the wet season and continued for 157 days into the dry season. The highest yielding legumes were C. ternatea in the wet season and Arachis sp. in the dry season. The mean rumen bag dry matter digestibility (RBDMD) of legumes of 67.6% for leaf material (averaged over all cycles and ages) was 7.6% higher than for stem material. The RBDMD of Arachis was significantly higher than all other species. The RBDMD of all legumes declined with age. Calculation of yield of digestible DM (yield $\times$ RBDMD) showed that Arachis sp. was the best legume. The combination of plant "quality" with yield measures is a valuable adjunct to routine agronomic survey procedures in plant evaluation programs. Arachis sp. appears to offer considerable promise and should be more widely evaluated.

ADAPTATION OF THE RUMEN BAG DIGESTIBILITY TECHNIQUE FOR USE IN GOATS
Bulo, D.,Till, A.R.,Blair, G.,Stur, W. Asian Australasian Association of Animal Productio 1992 Animal Bioscience Vol.5 No.4
Problems with maintaining service and equipment in some developing countries suggest that the rumen bag technique may be more appropriate for the determination of plant dry matter digestibility. The technique has been adapted for use in goats in the 16-25 kg liveweight range. Reliable results were obtained for animals maintained under shelter in cages and fed on a mixed legume/grass diet. The results showed that up to 7 bags containing dried and ground (2 mm screen) plant samples (1-3 g) could be satisfactorily used in each goat. The digestibility of the legumes studied did not increase with incubation times over 48 hours, but there was an increase in the digestibility of grasses. However an incubation time of 48 hours was adapted for both legumes and grasses as it allowed more efficient work scheduling for large numbers of samples while still giving acceptable comparisons between species. Losses of material from the bags during a 6 hour soaking in water were 2-9% as fine solids and 14-21% in solution. In the method finally adapted the disappearance was measured for plant samples that were placed in Dacron mesh bags ($7{\times}14cm$, 44 micron) and 6 bags suspended in the rumen of each sheep for 48 hours.

YIELD AND DIGESTIBILITY OF FORAGES IN EAST INDONESIA II. GRASSES
Bulo, D.,Blair, G.J.,Till, A.R.,Stur, W. Asian Australasian Association of Animal Productio 1994 Animal Bioscience Vol.7 No.3
This study was undertaken at Gowa, South Sulawesi, Indonesia, as part of a larger forage genetic resource evaluation project. The experimental program consisted of a field experiment where grass and legume species were grown in monocultures and the dry matter yield, rumen bag digestibility (RBDMD) and N content of leaf and stem components were monitored in the wet and dry seasons. Eight species of grass (Brachiaria decwnbens cv. Basilisk. Panicum maximum cv. Riversdale, Urochloa pullulans CPI 41192, Imperata cylindrica from Maiwa, South Sulawesi, Digitaria milanjiana CPI 41193, Cenchrus ciliaris cv. Malopo, Heteropogon contorlus and Setaria sphacelata cv. Splenda) were studied. P. maximum was the highest yielding grass in the wet season and B. decumbens in the dry season. The highest RBDMD in the whole plants were U. pulluians, P. maximum, S. sphacelata and D. milanjiana after 2 weeks regrowth in cycle I and S. sphacelata, B. decumbens, D. milanjiana and C. ciliaris in cycle 2. When total digestible DM was calculated for the whole of cycle I, P. maximum, B. decumbens and S. sphacelata were superior, but B. decumbens produced over twice as much as the other species in the dry season (cycle 2). The leaf N concentration of all grasses exceeded 1.0% (6.25% crude protein) in the regrowth in cycle I but did not exceed 0.5% in the dry season regrowth (cycle 2).

People hold diverse beliefs about the feeling and value of emotions; for instance, some people believe they should only feel happy and never feel depressed. Interestingly, previous studies have demonstrated that these beliefs are associated with increased depression. This raises questions about how such beliefs operate in a clinical setting; however, little research has been conducted on treatment-seeking individuals. We examined beliefs about the values of happiness and depressive feelings and their relationship to treatment outcomes in 289 adult patients admitted in an intensive cognitive-behavioral therapy-based psychiatric partial hospital program in the U. S. Beliefs related to happiness and depressive feelings were significantly reduced after treatment, suggesting that they are amenable to change. Moreover, a decrease in the belief that depression should never be experienced was uniquely associated with decreased depressive symptoms after treatment, even after accounting for demographic and treatment-related variables. Our findings support the idea that beliefs about the values of emotions, especially about feeling depressed, are potential targets for depression treatment.
